How to Unblock a File to Stop "Open File - Security Warning" and "Windows 8 SmartScreen" Prompt

information   Information
This will show you how to unblock a file that you have downloaded or copied from the internet or external source to no longer get the "Open File - Security Warning" or "Windows 8 SmartScreen" prompt when you open or run the file.

The Open File - Security Warning prompt is a security measure in Vista, Windows 7, and Windows 8 to ask for your permission (like UAC) before allowing a downloaded or copied file from the internet or another computer to be opened or run on your computer.

Windows SmartScreen, like the SmartScreen Filter in Internet Explorer, can help keep your whole computer safer by warning you before running unrecognized programs downloaded from the internet in Windows 8.

warning   Warning
You should only unblock files that you trust.


EXAMPLE: "Windows protected your PC" from Windows 8/8.1 SmartScreen

EXAMPLE: Open File - Security Warning
  • Do you want to open this File? Unknown Publisher
  • The Publisher could not be verified. Are you sure you want to run this software? Unknown Publisher
  • Do you want to run this file? Application

Open File - Security Warning : Unblock File OPTION ONE Open File - Security Warning : Unblock File
To Unblock the File Through Properties Page

NOTE: This option can only be done when the file or folder is still in one of your C:\Users\(user-name) folder locations. For example, your Desktop or Downloads folder. If it's not, then you will need to move the file to this location first, unblock it, then move it back.
1. While the file is on your desktop or in one of your user folders, right click or press and hold on the file, and click/tap on Properties.

2. Under the General tab, click/tap on the Unblock button, and click/tap on OK. (see screenshot below)
NOTE: If you do not see an Unblock button, then the file has already been unblocked.

3. You will now no longer get a Open File - Security Warning prompt when you try to open or run this specific file.



Open File - Security Warning : Unblock File OPTION TWO Open File - Security Warning : Unblock File
Unblock File when you Open or Run it and get "Open File - Security Warning"

NOTE: This option will unblock the file no matter where it's located.
1. Open or Run the file to trigger the Open File - Security Warning prompt.

2. In the Open File - Security Warning prompt, uncheck the Always ask before opening this file box, then click/tap on either the Open or Run button. (see screenshots below)

3. If prompted by UAC, then click/tap on Yes (Windows 7/8) or Continue (Vista), or enter the administrator's password (standard user).
NOTE: You will only be prompted by UAC if the file is not in one of the C:\Users\(user-name) folder locations, and in a system folder (ex: C:\Windows) instead.

4. The file will now open or run, and you will now no longer get a Open File - Security Warning prompt when you try to open or run this specific file next time.



Open File - Security Warning : Unblock File OPTION THREE Open File - Security Warning : Unblock File
Unblock File when you Open or Run it and get "Windows 8/8.1 SmartScreen"

NOTE: This option only applies to Windows 8 or 8.1. Doing OPTION ONE or OPTION TWO above will also unblock the file to no longer get the "Windows protected your PC" prompt from Windows 8/8.1 SmartScreen.
1. Open or Run the file to trigger the Windows protected your PC prompt.
NOTE: If you do not get this prompt, then the file has already been unblocked, and there's nothing else that needs to be done.

2. Click/tap on the More info link. (see screenshot below)

3. Click/tap on the Run anyway button. (see screenshot below)

4. The file will now open or run, and you will now no longer get a Windows protected your PC prompt when you try to open or run this specific file next time.
That's it,
Shawn

Hello Maciacia,

Yes, you could just turn off UAC, but this shows you how to stop this warning message for a file without disabling UAC protection for the entire computer.

Same problem, but no tick box

Hello!

I've got the same problem, but my dialog do not have the tick-box saying "Always ask before opening this file", nor do I have the button saying "Unblock" in the file properties dialog. What can I do?

Hello Mikke, and welcome to Seven Forums.

Could you post a screenshot of what you are getting?

In addition, what file is this for, and what is it's location?

Right click on the shortcut, and click on Properties, Shortcut tab, Open file Location button. Next, check that program's exe file to see if it's unblocked.

If the exe file is still unblocked after you unblocked it and checked again, then move the file to the desktop, unblock it at this location, and move it back.

Um, ok. Give this a try to see if it may help. It will reset the Internet Security Zone settings back to default.
  • Open a elevated command prompt (right click - Run as administrator)
  • Copy and paste the comand below and press Enter.
Code:
reg delete "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones" /f
  • Close the command prompt, and restart the computer to apply.
